Abstract
Grating-coupled surface emitting semiconductor lasers have been integr ated with focusing and spot array generating diffractive beam-forming elements, The lasers have an unstable resonator producing a 160-mu m-w ide single spatial mode. The area of the outcoupler element is 160 mu m x 240 mu m, For an outcoupler focusing at 500 mu m above the surface the spot size is 9 mu m x 17 mu m, The spot size is primarily limited by aberrations in the wavefront of the guided mode.
